I'm around to purchase a house near a furnace, and it uses automatic gas. I've get some question!? I have singular lived in homes next to plain old electricity...

I have singular lived in homes next to plain old electricity and a fry pump. So I don't know anything about unprocessed gas or furnaces.

Are there any danger associated with furnaces and raw gas?

Which one is better for the environment?

Which one is cheaper?

Is there anything else I should know roughly speaking furnaces or natural gas?
Answers:    Fireguy have a really good, correct answer for you. I and my wife own lived in a home for 50 years that have had two gas-fired central heating furnaces, and we never have any problems with any of them. We live in SW Louisiana where on earth natural gas is plentiful and USED to be much cheaper on our utility bills than electricity. We didn't own central Air Conditioning, though, but our home be constructed to eventually accommodate the addition of intermediate A/C. When we bought the new installation, we still stayed near the natural gas for the clean furnace (having an electric driven blower). with the cooling coil bag mounted on top and electrical outdoor compressor/fan-cooled heat exchanger component.

Now-a-days, though, the cost of natural gas have climbed to the point that it is almost as costly as electricity for heating a home. Still, where on earth we are located anyway, I feel that inborn gas is more DEPENDABLE than electricity. We've always have gas-fired hot water heaters surrounded by our home, also. I never had any problems next to the first one until it started getting loaded with water`s edge deposits and began developing leak around threaded galvanized piping. The second one, which we still own, has a unexpected 'for no apparent reason' irregular template of loosing the pilot light for the basic burner. Of course this causes an automatic 'tripping closed' on the prevalent gas supply valve; beside a required resetting the valve and re-lighting the pilot neutral -- BY HAND. This means getting down on one's knees to as close to the floor as possible and next to a lit long fireplace match or a hand-held, long snout propane lighter (MUCH preferred); reaching into the burner pilot lite tube while holding down on a button higher than the cutoff valve, set to 'start' position,; ignite the pilot and CONTINUING to hold down on the 'start' button while the fire sensing bulb heats up to a proper warmth (which usually takes more time than the average thrmb or finger can endure); and next, if you're EXTREMELY lucky, you can release the !#*(a)\ 'start' button and turn main spigot back on.
As long as the furnace is checked by a professional once a yr. , a gas furnace is more economical and more environmentally friendly. The menace is that you don't have the component serviced at the start of the heating season and own a hole in the warmness exchanger. That will allow CO to enter your living area. Your mortgage company will insist on a power-driven inspection before you close on the business. I wish you adjectives the good luck surrounded by the world in your hot home. May God Bless you and Yours.
